【正确答案】 E、O
【答案解析】根据句法分析，该空内容为该句主语，故为名词。再看意思，“The_______ wouldn''t have been necessary but for one simple fact．”(如果不是因为以下这个简单事实的话，这个“______”本来是没有必要的)。结合上段，我们可知所空内容指的是第一段中描述的规定。据此，我们可以确定[O]rule为该题答案。
【正确答案】 C、M
【答案解析】根据句法结构，该空应该是一个谓语动词；该句的意义为“即使在严重的交通事故中，系安全带可以使近 50%的人避免死亡，……”。所谓“避免死亡”即为“防止死亡发生”。为此，应该选用[M]prevent为该题答案。
【正确答案】 A、K
【答案解析】根据句法分析，可以确定该空应该是一个副词；根据意义，它应该是一个表示“严重”意义的程度副词。故，可以确定[K],seriously 为该题答案。
【正确答案】 I
【答案解析】根据句法和意思分析，我们可以看出，该语境是一个表示速度的表达方式，故应该确定[I]speed为答案。介词词组at a speed of only 30 miles per hour在句中充当状语。
【正确答案】 G
【答案解析】句法分析表明，该空是一个谓语动词；根据上文"Wearing a seat belt, saves lives"，我们可以知道下文中的“it指的还是“系安全带”，也就是说“系安全带可以减少一半的死亡和伤害”。故，应该确定[G]reduce为该题答案。
【正确答案】 E
【答案解析】空中所缺内容应该是一个逻辑副词。上文说到系安全带的好处。该句对上文进行总结，即：驾驶人员和 14岁以上的前排乘客必须系安全带。因此，应该选择表示“总结”意义的逻辑副词。故，[E]therefore (因此)符合要求。
【正确答案】 C
【答案解析】从句法来看，该空内容为一个渭语动词；从上下文的意义来看，该词的意思表示“乘坐”。故，[C]为该题答案。ride in a car (乘坐汽车)，ride in the front seats(坐在前排)。
【正确答案】 A
【答案解析】跟52题一样，该空又是一个逻辑副词。下文所说内容为可以不系安全带的几种情况。显然，这与上文构成转折关系。故，可确定[A]为该题答案。
【正确答案】 B
【答案解析】根据句法分析，我们可以确定该空内容应该与make构成习惯用法。该句的意思为“在你决定不系安全带之前，应该‘明确’上述不系安全带的规定适用于你”。故，应该确定[B]sure为该题答案。make sure that为固定用法意思是“务必查明、弄清楚”。
【正确答案】 D
【答案解析】句法分析告诉我们，该空的内容是一个介词宾语；该语境意思为，“Remember you may be taken to 56 for not doing so”(要记住如果你不系安全带就有可能被送上法庭)。根据语法和语义分析，我们可以确定[D] court (法庭)为该题答案。take somebody to court为动词习惯用语，常用于以下结构：take somebody to court for (not) doing something．
